by our College Data Analytics TeamUse the student to faculty ratio, as well as the faculty composition to get an idea of how much attention you'll receive as an individual student at Stony Brook University .
Student to faculty ratio is one of the standard metrics used to gauge the number of teaching resources a school provides for its students. With 18 students for every one instructional faculty member, Stony Brook University has more students split among the same faculty when compared to the national average of 15 . This metric might be an indicator that larger class sizes may be the norm, especially in introductory courses.
The following table shows all the employees the school considers instructional, and therefore, part of the above student-to-faculty ratio. These include both those employees designated as either "primarily instructional" or as "instructional combined with research/public service". It does not include employees that have been identified by Stony Brook University as primarily performing research or public service.

Colleges often use part-time professors and adjuncts to teach courses, rather than full-time faculty. This hiring practice is primarily a way to save money amid increasingly tight budgets. However, it is a controversial practice with strong views on either side. We encourage you to understand this topic more deeply, and how the colleges you are interested in approach faculty hiring. It's your education and your money on the line. Make sure you know what you are getting for it.
On this page, we refer to an adjunct teacher or a part-time teacher interchangeably, although each school may have a slightly different definition. In short, an adjunct professor can either work full-time or part-time during a school semester, but they have no contract or a contract that lasts only a short amount of time. To come up with the numbers for this page, we use the total number of part-time non-faculty and non-tenure track faculty to represent the count of adjuncts for the college or university.
Stony Brook University has 810 instructional graduate assistants that teach or provide teaching-related duties. These responsibilities could range from entirely teaching lower-level courses themselves, to assisting professors by developing teaching materials, preparing or giving exams and grading student work. We suggest you ask the college to what extent graduate assistants are relied on for instruction, so you know what you are paying for.
Additionally, the school has 161 non-instructional graduate assistants.
